- This invention appertains to tractors and more particularlyto attachments therefor for facilitating the guiding of the tractor f "down a field relative to the previously plowed furrows, so as to insure the proper spaclng and forming of all of the'furrow's.

One of the salient objects of mylnvention plowed, so that the steering wheels will be effectively guided relative to said prevlously plowed furrow means being provided for permitting the automatic raising of the guide into and out ofoperative position relative to said f'urrow. I

Another important object of my invention is the provision of novel means for connecting the guide both with the -swinging steering wheels of the tractor and with the frame of the tractor whereby the guide can be swung on either side'of the tractor to an operative position relative to a previously plowed furrow, without changing any ofthe'partsfof the guide or disconnecting the same in any way from the tractor. v s V v I A further object of my invention is the provision ofnovel me'ansfor forming the guide itself whereby the guide can be initially ad justed to conform to the spacing of the furrows. v i V r A still further objectof my invention is to provide a novel tractor guide, of the above character, which will embody a minimum,

numberof parts, which' will be durable and efficient in use, one that-@will be simple and easy to manufacture, and one which canbe placed upon the market. and incorporated with a conventional tractor at a minimum cost.

With these and other objectsin view, the

invention consists in the novel construction,

arrangement and formation of parts, as will be hereinafter more specifically described,

claimed, and illustrated in the accompanying drawings, in which drawings:

By the construction so far, it can be seen that the guiding deviceswings'with thefront axle 14 and that when the guide discs 24 are in their lowered position and in engagement I with a previously plowed furrow, that the axle 14 will be moved with the disc 25 as the 4 same follow the furrow.

The legs are rock- .a'bljy mounted on supporting brackets 38; and .39 carried by the tractor frame. The swing ing frame 35, islocated adj acent to the driv erfslseat and the. topbar 36 may constitute a jfootlrest' for thedriver for rocking said frame onthe shaft.
